    Summary
    Enables GTP binding activity and magnesium ion binding activity. Involved in several processes, including T-tubule organization; regulation of glutamate receptor clustering; and vesicle organization. Located in several cellular components, including endoplasmic reticulum exit site; type II terminal bouton; and vacuolar membrane. Is expressed in several structures, including adult ensheathing glial cell; brain; imaginal disc; mushroom body; and synaptic neuropil domain. Orthologous to several human genes including RAB2A (RAB2A, member RAS oncogene family). [provided by Alliance of Genome Resources, Dec 2024]
